Auxiliary Junction Box And Central Junction Box
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
The AJB controls, in conjunction with the CJB:
- The horns
- The liftgate latch motors and microswitches (including the liftgate external release switch)
- The liftgate ajar switch
- The turn signal indicators
- The fuel filler flap operation.
The AJB also has a connection to the RCM (restraints control module) for automatic operation of the interior lights and the turn signal indicators in the event of an accident.
The CJB and AJB are both fitted with an anti - theft sense line. If the AJB is disconnected when the alarm system is active, the full alarm will be activated by the CJB. If the CJB is disconnected when the alarm system is active, the AJB takes control of the security system and sounds the full alarm.
NOTE:
If the CJB is replaced, the new module will require configuring to the master car configuration using the IDS (Integrated Diagnostic System).
The CJB automatically arms and disarms the active anti - theft system when the vehicle is locked and unlocked after successful confirmation that a valid remote handset/smart key has been used.
